Throughout history man has had to accept the fact that all living things must die. Now people live longer than they used to. But all living things still show the effect of aging.
Aging is not a disease, but as a person passes maturity, the cells of the body and the organs they form do not work as well as they did when young. The body provides less protection against disease.
A number of causes may add to aging. Some cells of the body have a fairly long life, but they are not replaced when they die. As a person ages, the number of brain cells and muscle cells decreases. Other body cells die and are replaced by new cells. In an aging person, the new cells may not be able to grow as well as those of a young person.
Another factor in aging may be changed with the cells themselves. Some of the protein chemicals in cells are known to change with age and become less elastic. This is why the skin of old people wrinkles and hangs loose. This is also the reason why old people shrink in height.

Ask three people to look out the same window at a busy street corner and tell you what they see. The chances are you will receive three different answers. Each person sees the same scene, but each perceives something different about it.
Perceiving goes on in our minds. Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket. Another may say that he sees a rush-hour traffic jam at the crossing. The third may tell you that he sees a woman trying to cross the street with four children. Thus it can be seen that perception is the mind’s explanation of what the senses—in this case our eyes—tell us.
Many psychologists today are working to try to decide just how a person experiences or perceives the world around him. Using a scientific method, these psychologists set up experiments in which they can control all of the factors. By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene.
